<h3><u>Answer;</u></h3>

Luminosity and temperature of a star

<h3><u>Explanation;</u></h3>
  • <em><u>Hertzsprung-Russel diagram or HR diagram is a scatter plot or a graphical tool that is used by astronomers to classify stars based on their luminosity, color, temperature, spectral type  and also the stage of evolution.</u></em>
  • <em><u>The HR diagram plots the temperature of the stars against the luminosity, or the color of starts against absolute magnitude.</u></em>
  • The HR diagram is divided into stages, for example those stars at the stable phase of hydrogen burning are found within the main sequence according to their mass.

Inside the repetitive "loop," assuming that we use the final velocity in each time interval as the approximation to the average
Mumz [18]

Answer:

A. Calculate vector

B. Update vector of each object

C. Update position of each object

Explanation:

Taking assumption of a system in which the forces are a function of the previous step's final position:

Firstly, we calculate the (vector) forces acting on the objects.

Secondly, Update the (vector) momentum of each object

(note: also update the velocity).

Thirdly, Update the (vector) position of each object.

The other operations are as follows;

i. select (dt),

ii. define mass,

iii. Put down constants,

iv. initialize variables, this would occur before the time-step loop is entered.

Haley is driving down a straight highway at 73 mph. A construction sign warns that the speed limit will drop to 55 mph in 0.50 m
skad [1K]

Answer: a= -1029.97 m/s^{2}

Explanation:

We know Haley is driving with an initial velocity of V_{o}=73mi/h and then she has to change to a velocity of V_{f}=55mi/h in a distance d=0.50 mi, and we also know we are dealing with constant acceleration  a.

Therefore, the following equation will be useful:

{V_{f}}^{2}={V_{o}}^{2}+2ad (1)

Clearing a:

a=\frac{{V_{f}}^{2}-{V_{o}}^{2}}{2d} (2)

a=\frac{{(55mi/h)}^{2}-{(73mi/h)}^{2}}{2(0.50 mi)} (3)

a=-2304 mi/h^{2} (4)

Knowing 1h=3600 s and 1mi=1609.34 m:

a= -1029.97 m/s^{2} this is the constant acceleration that will bring Haley to lower speed

1. A person is lifting a suitcase into the trunk of a car. Assuming the suitcase is already in the air, draw the FBD and write t
Alik [6]

Answer:

Explanation:Assume you are lifting an object with mass 20 kg from the ground to a height of 1.5 m.  Assume that you are exerting a constant force in the upward direction and that you are moving the object upward with uniform velocity.  The net force on the object is zero.  The force you are exerting is equal in magnitude and opposite in direction to the force of gravity.  As you are lifting the object you are doing work on the object.
